TECHNICAL FIELD

[0001] The utility model relates to punch technology field especially relates to a punch die waste discharge mechanism. BACKGROUND

[0002] In the cold punch die, the size of the part piece is usually larger than the size after forming, so the waste outside the part needs to be trimmed. Because the waste of one-time blanking is large, it cannot fall smoothly into the waste pit, so secondary shearing needs to be designed.

[0003] In the part produced by the cold punch die, the outer cover uses the secondary shearing method to trim the waste. For secondary shearing, the past die generally uses the way of casting guide and limiting device cooperation. When stamping, the part is put into the material, and the material is placed on the convex die. With the progress of the stamping work, the upper die is pressed down, the upper die is pressed first, the upper die continues to act downward until the upper die cutter block contacts the material, completes the first blanking, realizes the separation of the part and the waste, and the waste is blocked by the limiting device with the casting guide. In the next stamping process, the waste blocked by the limiting device is sheared into small pieces by the waste cutter of the upper die, and then falls into the waste pit of the stamping table. The existing die causes the waste to slide unsmoothly due to the small casting sliding angle, which affects the stamping production efficiency, so the part production cost is relatively high. At the same time, due to the small waste sliding angle, the waste is easy to be stuck, and the die may be damaged.

The guide sliding device of the patent comprises a third mounting seat and a guide sliding rod, the guide sliding rod is fixed on the lower die seat through the third mounting seat, the guide sliding rod plays a role of guiding sliding, and is used for guiding and sliding the cut long edge waste to the lower second waste knife assembly, therefore, the guide sliding rod needs to be arranged obliquely, and the end close to the male die is higher than the end close to the lower second waste cutting knife assembly, so that the long edge waste can be smoothly slid to the lower second waste cutting knife assembly. Due to the limitation of die feeding height, the lower die seat cannot be designed too high, resulting in that the angle of the casting sliding rod is not enough, the once-cut waste cannot be smoothly slid to the second cutting position, waste is accumulated, the next stamping is affected, and the die is damaged.

The guide and slide device of this embodiment is rotatably connected with support seat 4 through guide and slide piece 5, and one end of guide and slide piece 5 close to limiting device 3 is heavier than its one end away from limiting device 3, when stamping, material piece 6 is placed on male die 2, material piece 6 will be pressed in the one end of guide and slide piece 5 away from limiting device 3, since the weight of material piece 6 is greater than the one end of guide and slide piece 5 close to limiting device 3, so the one end of guide and slide piece 5 close to limiting device 3 will be tilted, with the progress of stamping work, upper die is pressed down, upper pressure material is pressed in material piece 6, continues to move down, until upper die cutter block contacts material piece 6 and carries out once blanking, material piece 6 is divided into part 601 and waste 602, waste 602 is in the one end of guide and slide piece 5 away from limiting device 3, at this moment, since the one end of guide and slide piece 5 close to limiting device 3 is heavier, makes the one end of guide and slide piece 5 away from limiting device 3 tilt, thereby the inclination angle of guide and slide piece 5 increases, further greatly improves the sliding angle of waste 602, makes the sliding of waste 602 more smooth, prevents the accumulation of waste 602 of mould, prevents the damage of mould, and can improve the production efficiency of part 601.

[0029] Example two

[0030] The difference between this embodiment and example one is that, on the basis of example one, the guide and slide piece 5 is further described in this embodiment.

[0031] In this embodiment, guide and slide piece 5 includes guide and slide part 501 and counterweight part 502, guide and slide part 501 is rotatably connected with support seat 4, and counterweight part 502 is connected to the one end of guide and slide part 501 close to limiting device 3. By dividing guide and slide piece 5 into guide and slide part 501 and counterweight part 502, the direction installation error of guide and slide piece 5 can be prevented, and the installation of guide and slide piece 5 is more convenient, at the same time, the connecting place of counterweight part 502 and guide and slide part 501 forms a force arm to the connecting place of guide and slide part 501 and support seat 4, which is beneficial to achieve the effect of prying the end of guide and slide piece 5 carrying waste 602 by using the counterweight part 502 with smaller weight.

[0032] Further, the counterweight part 502 and guide and slide part 501 of this embodiment are arranged at a certain angle. The length of guide and slide piece 5 can be shortened, the mold can be prevented from being too large, and the distance of waste 602 sliding can be shortened, and the failure of waste 602 sliding can be further prevented.

[0033] In addition, the included angle between the counterweight part 502 and the guide part 501 is obtuse, so that the rotation range of the guide member 5 is large.

[0034] Specifically, the counterweight part 502 includes a connecting arm 5021 and a weight 5022, one end of the connecting arm 5021 is connected with the guide part 501, the other end of the connecting arm 5021 is connected with the weight 5022, and the connecting arm 5021 is arranged at an obtuse angle with the guide part 501.

In addition, the guide part 501 and the weight 5022 are located on both sides of the connecting arm 5021, so that the rotation range of the guide member 5 is large, thereby ensuring that the waste 602 has a larger sliding angle. If the guide part 501 and the weight 5022 are located on the same side of the connecting arm 5021, the weight 5022 will be blocked by the punch 2, and the larger the volume of the weight 5022, the smaller the rotation angle of the guide member 5. Therefore, in this embodiment, the guide part 501 and the weight 5022 are arranged on both sides of the connecting arm 5021, so that the volume of the weight 5022 can be larger to ensure the weight. In this embodiment, the weight 5022 has a right trapezoidal structure, the connecting arm 5021 has a rectangular structure, and the short side of the weight 5022 is connected with the short side of the connecting arm 5021. The length of the short side of the connecting arm 5021 is equal to the length of the short side of the weight 5022.

[0038] In this embodiment, the support seat 4 is provided with a stop block 401, which is located below the connection between the guide member 5 and the support seat 4. The stop block 401 functions to limit the rotation angle of the guide member 5, preventing the guide member 5 from rotating too much and causing the material 6 to not press on the guide member 5 when being fed.

[0039] Further, one end of the stop block 401 close to the limiting device 3 is provided with an inclined surface 4011, which is inclined away from the connection between the guide member 5 and the support seat 4 in the direction close to the limiting device 3. When the guide member 5 rotates, the one end of the guide part 501 connected with the counterweight part 502 is attached to the inclined surface 4011. The arrangement of the inclined surface 4011 can reduce the impact of the stop block 401 on the guide member 5, preventing the guide member 5 from being blocked by the stop block 401 when rotating and causing damage to the guide member 5. In addition, the stop block 401 is rotationally connected with the support seat 4, so that the angle of the stop block 401 can be adjusted, thereby adjusting the rotation angle range of the guide member 5.

The end of the support base 4 close to the limiting device 3 is closer to the limiting device 3 than the end of the guide sliding piece 5 close to the limiting device 3, so that the guide sliding piece 5 extends out of the support base 4, and the rotation of the guide sliding piece 5 can be prevented from being hindered by the support base 4. The support base 4 comprises a first support part 402 and a second support part 403 connected with each other, the first support part 402 is connected with the punch 2 through bolts, the height of the second support part 403 is greater than that of the first support part 402, the guide sliding piece 5 is connected with the second support part 403, and the connecting part of the guide sliding piece 5 and the second support part 403 is higher than the top surface of the first support part 402, and the stop block 401 is arranged on the side surface of the second support part 403 and protrudes outward, and the stop block 401 and the guide sliding piece 5 are located on the same side of the second support part 403.

[0041] In addition, the limiting device 3 is a limiting column, the limiting column is connected with the secondary waste cutter 8 of the lower die base 1, the waste 602 during stamping falls onto the secondary waste cutter 8 through the guide sliding device and is blocked by the limiting device 3, and the waste 602 is sheared again under the action of the upper die and the secondary waste cutter 8 during the next stamping, so that the waste 602 is sheared into small pieces.

[0042] The other structure of the embodiment is the same as that of the second embodiment, and details are not repeated here.

[0043] In conclusion, the stamping die waste 602 discharge mechanism provided by the embodiment of the utility model, the guide sliding device is rotatably connected with the support base 4 through the guide sliding piece 5, and the end of the guide sliding piece 5 close to the limiting device 3 is heavier than the end of the guide sliding piece 5 away from the limiting device 3, during stamping, the material piece 6 is placed on the punch 2, and the material piece 6 is pressed on the end of the guide sliding piece 5 away from the limiting device 3, because the weight of the material piece 6 is greater than that of the end of the guide sliding piece 5 close to the limiting device 3, so the end of the guide sliding piece 5 close to the limiting device 3 is lifted, the upper die is pressed down during stamping, the upper die presses the material piece 6, and the upper die continues to move downward until the upper die cutter block contacts the material piece 6 to perform once blanking, the material piece 6 is divided into a part 601 and a waste 602, the waste 602 is on the end of the guide sliding piece 5 away from the limiting device 3, at this time, because the end of the guide sliding piece 5 close to the limiting device 3 is heavier, the end of the guide sliding piece 5 away from the limiting device 3 is lifted, so that the inclination angle of the guide sliding piece 5 is increased, and the sliding angle of the waste 602 is greatly improved, the waste 602 slides more smoothly, the waste 602 of the die is prevented from being accumulated, the die is prevented from being damaged, and the production efficiency of the part 601 is improved.
